There is a lot of it and most of its good, some is bad and some is just bizarre.
This guy has been downtown the last couple of weeks. He draws a crowd because of the look (how can you miss him) but unfortunately his playing still needs (a lot of) work so people rarely stay longer than it takes to click their phone.
I have a short video of him but I won't subject you to it. I'll try to add some more street music options as I come across them.
